ATLANTA, GA – A new study from the Centers for Disease Control and Prevention (CDC) has revealed the remarkable success of the human papillomavirus (HPV) vaccine in preventing precancerous cervical lesions. The findings, published in the CDC’s Morbidity and Mortality Weekly Report, highlight the vaccine’s significant impact since its approval in 2006.
HPV, the most common sexually transmitted infection, can lead to various cancers, including cervical cancer. The CDC’s Human Papillomavirus Vaccine Impact Monitoring Project has tracked precancerous cervical lesion trends since 2008 to assess the vaccine’s effectiveness.
The study’s results are striking. Among women aged 20-24, rates of moderate-to-high-risk precancerous lesions decreased by approximately 80% between 2008 and 2022. For women aged 25-29, the decline was 37%, attributed to later “catch-up” vaccinations, which are less effective.
The HPV vaccine, initially approved for girls and women in 2006 and later for boys and men in 2011, is now recommended for routine vaccination of boys and girls aged 11-12.
“The data are consistent with a considerable impact from the US HPV vaccination program on cervical precancers, with the largest decreases in the youngest age group for which benefit of vaccination would first be observed,” the study authors wrote.
The researchers anticipate further declines in precancerous lesions as vaccinated women age. While individual vaccination status was not recorded, the authors stated that “no other plausible explanations” have been identified for the sharp decline.
The study’s findings come amidst ongoing discussions regarding vaccine advocacy, particularly following recent events involving US health policy.
The US Preventive Services Task Force recommends regular cervical cancer screenings, including Pap smears and high-risk HPV tests, for women aged 21-65.
